Solution

The correct options are
C ${3 M n O_{4}}^{2 -} + 4 H^{+} ⟶ {2 M n O_{4}}^{-} + M n O_{2} + 2 H_{2} O$
D $C u^{+} ⟶ C u^{+ 2} + C u$

Disproportionation is a type of redox reaction in which a single species undergoes both oxidation and reduction.

Oxidation State: +1 +2 0
Reaction: $C u^{+} ⟶ C u^{+ 2} + C u$

+6 +2 +4
${3 M n O_{4}}^{-} + 4 H^{+} ⟶ {2 M n O_{4}}^{-} + M n O_{2} + 2 H_{2} O$
